The electrical conductivity of a substance depends on the ability of the ____ in it to move. A) electrons B) neutrons C) protons
musickatia [10]

The correct answer to the question is A) Electrons.

EXPLANATION:

The electrical conductivity of a metal or any substance depends on the free electron concentration of the metals.

Free electrons are those electrons which are present in the conduction band of the metals. These electrons experience less amount of force attraction from the nucleus. Protons and neutrons do not  contribute anything to the current conduction in a metal.These sub atomic particles are bound to the nuclei of atoms.

When we maintain potential difference across the two ends of a conductor, the free electrons are drifted towards the positive terminal of the battery.

Hence, electrical conductivity of a substance is the ability of the electrons to move inside the substance.

More is the conductivity of the substance, the lesser is the resistance to the flow of electrons inside the substance, and vice versa.

When used as an energy source in a nuclear power plant, uranium is burned in a similar way as one would burn wood or coal for en
zavuch27 [327]
False because nuclear fission is used on uranium in nuclear power station and this reaction is continuous since a neutron hits a uranium atom and splits it. Then 2-3 neutrons are released which continues the cycle or hitting other uranium atoms. If this reaction isn't contained, it could get out of control and become a nuclear bomb. So it can't be burned like wood nor coal.
Hope this is helpful. <span />

What’s the dependent variable?
Nikolay [14]

Answer: number of bacteria

Explanation:

A easier way. I like to remember it is that x axis = independent and yaxis = dependent variable, but if that doesn’t help think about this

Why would the number of bacteria effect the amount of time. It doesn’t make sense because time goes on forever and nothing can change about it but time can change the number of bacteria because if you had a timer of 30 seconds and the bacteria is for example 10 and if you had a timer of one minute then the number of bacteria change because of time, if you flip it, it doesn’t make sense

A 20-kg block slides down a fixed rough curved track The block has a speed of 5 0 m/s after its height above a horizontal surfac
Crank

Answer:

U = 102.8 J (100 J to two significant digits)

Explanation:

potential energy converted = 20(9.8)(1.8) = 352.8 J

kinetic energy at base of track = ½(20)5.0² = 250 J

energy (work) of friction 352.8 - 250 = 102.8 J
